[linux-usb-devel] [PATCH] Maxtor OneTouch button support for older drives
Hi! This small patch adds a device ID used by older Maxtor OneTouch drives (the ones with blue face-plate instead of the fancy silver one used in newer models). The button on those drives works well with the current driver. -- Antti Andreimann - Security Expert Using Linux since 1993 Member of ELUG since 29.01.2000 --- ./drivers/usb/storage/unusual_devs.h.orig 2005-11-14 06:35:03.0 +0200 +++ ./drivers/usb/storage/unusual_devs.h 2005-11-14 06:35:22.0 +0200 @@ -976,6 +976,11 @@ * */ #ifdef CONFIG_USB_STORAGE_ONETOUCH + UNUSUAL_DEV( 0x0d49, 0x7000, 0x, 0x, + Maxtor, + OneTouch External Harddrive, + US_SC_DEVICE, US_PR_DEVICE, onetouch_connect_input, + 0), UNUSUAL_DEV( 0x0d49, 0x7010, 0x, 0x, Maxtor, OneTouch External Harddrive,

See if this version behaves for you. I tested the patch with 2.6.11.

It probably is an ISO-IN transaction, and opening sound device in output only mode does produce exactly the same error. I don't know exactly, but I suspect that some inbound data is used for synchronization in snd_usb_audio driver. Where can I get those patches You referred to? I'd be glad to test them. -- Antti Andreimann - Security Expert Using Linux since 1993 Member of ELUG since 29.01.2000 --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.

Send stack traces and I can offer suggestions; they'd be the best indicators that anything's wrong! Ok, I've attatched a crash log I produced yesterday. It's done with preemption enabled and unfortunately with no USB debugging turned on. I'll try to produce some more reasonable crash logs today after work. Kernel is 2.6.11 with software suspend 2.1.8 patches. PS!

[linux-usb-devel] What's wrong with iso-IN split transactions?
Hi! I see from the drivers/usb/host/ehci-sched.c that those are not supported. I also found a year-old post in this list by David Brownell which states: It's essentially all coded, but microframe scheduling needs tweaks for the IN cases. I decided to force ENOMEM until that code is ready ... someone willing to play with the code could turn it on and shouldn't find it needs many changes. What is the status of this stuff now? Has anyone done any work on this and what exactly is the problem with current code? I did try to turn it on for my USB soundcard (so it would work through a USB 2.0 hub) and experienced a NULL pointer dereference plus some spinlock errors. I haven't tried it without pre-emption yet. I am willing to spend some time to tweak and test it if I'd know what exactly needs tweaking ;) -- Antti Andreimann - Security Expert Using Linux since 1993 Member of ELUG since 29.01.2000 --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.
